New SP-Caps need no derating; eliminate risk of fire

Munich, January 2015: Panasonic Automotive & Industrial Systems has introduced three new high voltage members of its SP-Cap range of speciality conductive polymer aluminium capacitors. CS, CT, CX capacitors range in voltage from 10-35V, and target input side circuitry, especially in industrial applications.

Polymer capacitors feature ultra-low ESR values, resulting in a low impedance near their resonance point which helps to smooth ripple voltage in power circuits. Unlike ceramic devices, polymer devices suffer no capacitance drift due to temperature changes and DC bias, so they remain stable. They also have a self-healing capability that eliminates failures due to cracking in the dielectric layer caused by electrical or mechanical stresses.

For input-side designs, high ripple current and small size are important. The 35V SP-Caps have a ripple current of 3.2Arms and stand as little as 1.1mm above the PCB. They offer a high capacitance of 10 to 22µF at 35V and constant operation at 35V is possible. As no voltage derating is necessary, these new SP-CAPs can easily be used for 24V to 28V input line designs.

Comments Melanie Raimann, European Product Manager for Polymer Capacitors at Panasonic: “We can ensure 10 year lifetime at 85degC for these devices; a further advantage over conventional MnO₂ tantalum capacitors is that SP-CAPs cannot ignite, so they are therefore a very interesting alternative to MLCC, MnO₂ tantalum or aluminium electrolytic products.”
